Answer 1

Explicação passo-a-passo:

$1 \dfrac{1}{5} \times - \dfrac{2}{3} + 1 \dfrac{1}{5}$

$\dfrac{1 \times 5 + 1}{5} \times - \dfrac{2}{3} + \dfrac{1 \times 5 + 1}{5}$

$\dfrac{5 + 1}{6} \times - \dfrac{2}{3} + \dfrac{5 + 1}{5}$

$\dfrac{6}{5} \times - \dfrac{2}{3} + \dfrac{6}{5}$

$- \dfrac{12}{15} + \dfrac{6}{5}$

$\dfrac{ - 12 + 18}{15}$

$\dfrac{6}{15}$

$\dfrac{6 {}^{ \div 3} }{15 {}^{ \div 3} }$

$\dfrac{2}{5}$
